General Description
The MAX1183 is a +3V, dual 10-bit analog-to-digital
converter (ADC) featuring fully differential wideband
track-and-hold (T/H) inputs, driving two pipelined, nine-
stage ADCs. The MAX1183 is optimized for low-power,
high dynamic performance applications in imaging,
instrumentation, and digital communication applica-
tions. This ADC operates from a single +2.7V to +3.6V
supply, consuming only 120mW while delivering a typi-
cal signal-to-noise ratio (SNR) of 59.6dB at an input fre-
quency of 20MHz and a sampling rate of 40Msps. The
T/H driven input stages incorporate 400MHz (-3dB)
input amplifiers. The converters may also be operated
with single-ended inputs. In addition to low operating
power, the MAX1183 features a 2.8mA sleep mode as
well as a 1µA power-down mode to conserve power
during idle periods.
An internal +2.048V precision bandgap reference sets
the full-scale range of the ADC. A flexible reference
structure allows the use of this internal or an externally
derived reference, if desired for applications requiring
increased accuracy or a different input voltage range.
The MAX1183 features parallel, CMOS-compatible
three-state outputs. The digital output format can be set
to two’s complement or straight offset binary through a
single control pin. The device provides for a separate
output power supply of +1.7V to +3.6V for flexible inter-
facing. The MAX1183 is available in a 7mm 7mm, 48-
pin TQFP package, and is specified for the extended
industrial (-40°C to +85°C) temperature range.
Pin-compatible lower and higher speed versions of the
MAX1183 are also available. Refer to the MAX1180
data sheet for 105Msps, the MAX1181 data sheet for
80Msps, the MAX1182 data sheet for 65Msps, and the
MAX1184 data sheet for 20Msps. In addition to these
speed grades, this family includes a multiplexed output
version, for which digital data is presented time-inter-
leaved and on a single, parallel 10-bit output port.
